The preference of adults Tribolium castaneum to different colour cues were evaluated with multi choice and single choice test at 24, 48 and 72 hours after insect release. In multi-choice test, seventy two hours after release highest preference of T. castaneum was recorded in Violet (13.80%), followed by Indigo (12.20%) and green color cues (2.13%) were the least preferred whereas, single-choice experimental highest preference of T. castaneum was noticed in violet (25.80%) followed by Indigo (25.27%) and green color cues (15.87%) were found to be the least preferred.
